Ground Resistance Tester Model 4620

Cat. #2130.43
Range 0.01 to 2000Ω, Resolution 0.001 to 10Ω, 4-Point test
The Digital Ground Resistance Tester Model 4620 performs ground resistance and soil resistivity tests. This direct reading testers measures from 0 to 2000Ω, and is auto-ranging, so it automatically seeks outs the optimum measurement range.

The Ground Resistance Tester Model 4620 is also available in complete Kits (150ft, 300ft & 500 ft).

Ground Resistance Tester Model 6424 (Digital, 3-Point)

Cat. #2135.57
Range 0.5 Ω to 50 kΩ for 3-point ground resistance (3P mode), 0.05 Ω to 50 kΩ for 2-pole resistance (2P mode), Automatic Test Current 20 mA max, ±10 V peak open Voltage, >1500 measurements @100 Ω in 3 P mode

The Digital Ground Resistance Tester Model 6424 performs 2-pole and 3-pole ground resistance measurement. This direct reading tester is auto-ranging, so it automatically seeks out the optimum measurement range.
